SIEGISMUN D LOEVVENTHAL, OF ACTON, COUNTY OF MIDDLESEX, ENGLAND.

MANUFACTURE OF ORNAMENTAL WALL-COVERING, LEATHER-CLOTH, dc.

SPECIFICATION forming part of Letters Patent No. 327,286, dated September 29, 1885.

Application filed July 6, 1885. (No specimens.) Patented in England June 14, 1884, No. 9,025.

To all whom it may concern:

Be it known that I, SIEGISMUND LOEWEN- THAL, a subject of the Queen of Great Britain, residing at Acton, Middlesex, England, have invented new and useful Improvements in the Manufacture of Ornamental VVall-Ooverings, Leather-Cloth, and the Like, and in compositions used therein, (for which I have obtained a patent in Great Britain, No. 9,025, bearing date June 14, 1884,) of which the following is a specification.

The object of thisinvention is to compound certain ingredients together to form a plastic adhesive body capable ofbeing spread or rolled upon a canvas or other backing to any desired thickness, and which can be printed in plain or many colors,or metallized to produce ornamental or decorative eii'ects, either plain or en1bossed,and with or without an exterior or surface sheet of canvas, according to the use the material so prepared is intended for.

The material is particularly adapted for wall decoration, imitation leather, floor-cloth, and other useful purposes. For this purpose I employ a composition of which Airman fl is the chief ingredient. sition upon a fabric, paper, or card-board, and after a pattern is printed on its surface, by means of blocks, rollers, or any other known process, I cause the material to be embossed by means of a die and pressure or rollers on the surface of which a design is engraved. The material is after this hung in a heated 300m for a considerable period in order to get The compound is composed of one hundred pounds of African flake, ten pounds of rubber, one hundred pounds of rubber substitute, ten pounds ofozocerite, one hundred-weight of infusoria, and one hundred-weight of wo0d-pulp or ground cork. Add to this two and onehalf per cent. of sulphuric acid and five per cent. muriatic acid. All these materials in their various proportions I mix in a mixing-ma chine, and after amalgamating them thoroughly I spread the compound on fabric, pa per, or card-board, by means of a calender, to a suitable thickness. In some cases I spread a very light fabric on the surface of the compound.

This can be printed in the same manner as wall-papers are generally printed, and when the colors are thoroughly dry I bring the whole under a press, on the top platen of which an engraved die is secured correspond ing with the pattern printed on the surface of the material. I place the printed pattern directly under the die, and by means ofthe pressure caused by the press I emboss the printed pattern on the material. On floor-clothIomit the latter process. On leather-cloth I emboss the material either with or without the printed pattern, which is also the case with wall decorations when desirable. After this process is completed I expose the material to a heat of from 80 to 180 Fahrenheit.

\Vhat I claim, and desire to secure by Letters Patent of the United States, is-

1. The hereinbefore-described process of ornamenting fabrics, consisting in applying to the surface thereof a compound composed of African flake, rubber, rubber substitute, ozocerite,infusoria, wood-pulp or ground cork, and sulphuric and muriatic acids in about the proportions specified, then printing upon the same patterns Or'designs, and finally drying the printed fabrics, substantially as set forth.

2. The process hereinbefore described of ornamenting fabrics, consisting in applying to the surface thereof a compound composed of African flake, rubber, rubber substitute, ozocerite,infusoria, wood-pulp or ground cork, and sulphuric and muriatic acids in about the proportions specified, then printing patterns or designs thereon, then embossing the same by means of dies or rolls having thereon designs or patterns corresponding with the printed designs or patterns, and finally drying the fabric, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
